AbstractIn this research, the amine functionalized magnetic silica‐based nanocomposite as a solid‐phase extraction adsorbent coupled with high‐performance liquid chromatography was applied for the preconcentration and determination of Sudan dyes in environmental waters and a food sample. The synthesized core‐shell Fe3O4@silica nanoparticles were functionalized with amino groups and characterized by scanning electron microscopy, energy‐dispersive X‐ray spectroscopy and Fourier transform infrared spectroscopy techniques. The experimental parameters optimized and under the best conditions, the sorbent was successfully used to extract the target analytes. The result showed that a good linearity with a r‐value of greater 0.990, and the limits of detection were from 0.082 to 0.12 µg L−1. The relative recoveries obtained by analysing the spiked water samples were in the range of 90–102% and the relative standard deviations were between 0.590 and 7.94%.

"Marcasciano's memoir sheds light on her experience in left-wing movements in Italy during the 1970s and early 1980s, at the outset of which 'coming out' was not yet a phenomenon in Italy and many preferred or were forced to repress their non-normative identities for fear of social repercussions. She details her trajectory toward an increased awareness of her sexuality. During her time in the cosmopolitan cities of Naples, Rome, and Bologna, she engages in consciousness raising and eventually succeeds in uniting the personal and the political, a practice that was common to women and people of queer identities. The book ends when AIDS hits Italy in the early 1980s. Marcasciano's memoir is one of few Italian texts to meticulously map out the main movements and political struggles of the 1970s and '80s from a queer perspective. Furthermore, AntoloGaia is the first work of Italian literature to use gender-inclusive language, a practice that is only starting to be taken seriously in Italy at the present time"--

Abstract
Background Intracranial aneurysms are more commonly associated with inflammation as a cause of their development, progression, and rupture. Macrophages and other cells can express the CD68 antigen. The aim of this study was to assess the CD68 antigen levels in cerebral aneurysm (CA) patients compared to a control group at a referral center in Iran.
Methods A case-control investigation was undertaken on 88 individuals (44 of whom were cases and 44 were controls). Individuals with CA as the case group consisted of 28 ruptured and 16 unruptured subgroups. Clinical, radiographic, and CD68 levels were evaluated and registered.
Results The average age of the participants was 49 years. Males comprised 43.2% of the patients, while 56.8% were females (p = 0.002). There was a statistically significant difference in the CD68 levels between the two groups. There was no significant difference (p = 0.42) between the ruptured and unruptured subgroups (23.66 and 20.47, respectively) in this comparison. No significant correlation was seen between the patients' CD68 and Glasgow Coma Scale (GCS) levels and their aneurysm diameter (p = 0.74 and 0.45, respectively). A link between CD68 levels and age was found, but it was not statistically significant (r = 0.44 and p = 0.002).
Conclusions A possible involvement of CD68 as an inflammatory agent in the development of CAs but not in aneurysm rupture has been suggested. Inflammation and CD68 were positively associated with age. The CD68 antigen should be studied further in population-based cohort studies.
